11 into the chamber (Z. The movement con tnnnng a quarter turn, the gasin the chambcr (Z is moved torward into the explosion chamber a, while anewcharge has been con-' ducted into the chamber cl for compression. Thegroove in the rotor face allows the gas to flow from thecompression'into' the combustion chamber over the top of the rotor whenthe piston 12 passes beyond the arrow 6, and permit the ignited gases toexpand. in the wider chamber 6, and be exhausted when that piston haspassed the ports to the discharge pipes 33 and 3 The further movement ofthe rotator will serve to force a supply of gas from the pocket 10through the duct 2% into the chamber a; and as the roto'r movementcontinues and the portion of the rotor body which serves as a wall forthat chamber gradually approaches the casing wall the area of thechamber is correspondingly diminished, producing a partial compressionof the contained gas; and when the rotor movement has continued to thepoint where the chamber a of Fig. 1 has taken the place of the chamber(Z, the compression willbe complete and a further movement will allowthe charge of compressed gas to flow into the explosion cham- To coolthe engine, communicating water passage-ways are provided. For coolingthe rotor, in its opposite sides are provided circular channels 37 and38, respectively. With the channel 37 is connected an inlet pi e 37, andfrom the channel a duct 39 exten s to one of a series of water-chambers40 provided in the rotor body which are connected by ducts 41. From thelast chamber of the series a duct 42 communicates with the channel 38 inthe rotor, and a discharge pipe 43 conducts the water from the latterchannel. The pipe 43 may be connected to a pump 44, which operates bysuction to introduce the water to the rotor chambers From the pump apipe 45 extends to one of av series of connected water-chambers 46 inthe head 4; which are coiinected by a duct 47 with a series of chambersl8 in the cylinder 1; and the latter chambers communihate by a duct 4-9with a series of chambers 56) in the head 3, from which the water isdischarged through a pipe'5l. 'By this arrangement the water isconducted first through the rotor adjacent .to the senses chambers, nextthrough the chambers of one of the heads, next through the cylinderchambers, and lastly through the chambers of the second head, whence itis discharged.

To prevent the leakage or gas or water between the rotor and cylinderheads, the

latter are provided with the usual packing rings 52 which bear againstthe-rotor sides gas and water channels 22, 37, and 38.. x

While I have shown and describedan engine having four pistons and acorresponding number of intermediate chambers, I do not limit myself tothe employment of that number; for, obviously, their number may beincreased or diminished to produce a greater or less number ofexplosions in a cycle, without changing the plan of operation. 7

Having described my invention, what I claim and desire to secure byLetters Pat-- out is-- Y It. In a rotary explosive engine, a cylinder, acylindrical rotor mounted eccentrically therein and in contacttherewithat one point and provided with a circumferential groove and pockets inits face and providing within its body ducts for vconductin .gas to thepockets and ducts for conducting it thence to the space between therotor ,andcylinder, valves for controlling the of gas through saidducts, pistons adapted to reciprocate in the pockets for introducing anddischergin the gas, and springs for holding the pistons in frictionalcontact with the cylinder, substantially as set forth.
